IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 38,4] 7, dated May 5, 1863., o

To aZZ whom it may concer'n: o

.Be it known that I, GEORGE O. ROUNDEY, ofthe city, county, and State of NewYork, have invented a new and useful Improvement in Gas-Burners; and I do hereby declare that the following is a full, clear, and exaot description of the same, reference being had to the accompanyin g drawings, formin g a part of this specification, in which- Figure 1 is a central Vertical section of myimproved burner, showing it applied over an ordinary burner. Figs. 2, 3, and 4 are central vertical sectons of the separate parts of which my burner is composed. Fig. 5 is a central vertical section of a burner exhibiting a modification in the construction of my invention.

Similar letters of reference indicate corresponding parts in the several figures.

.This invention relates to that kind of burner which is placed like a cap over an ordinary burner 5 and it consists in the combination of a tube, a globular eXpanding-chamber, and a tip, substantially as hereinafterdescribed.

A is the tube, B the expanding-chamber, and O the tip. The tube A and chamber B are made of one piece, as shown in Fig. 2, by spinning them from a piece of metal tubing of suitable size, or by other means, the tube being made of a form and size to'fit over the upper partof au ordinary burner, and the chamber being enlarged in globularform. The tip O has the orifices b b, for the issue of the gas, constructed and arra-nged as in an 'ordinary fish-tail burner, made separately and inserted and sec'ured in a central opening in the top of the chamber, above which it stands up to the height of about a quarter of an inch.

Figs. 1, 3, and 4 represent the tip, made of two .pieces of brass-viz., a tube, a, and a fianged inverted cone, b, the flange 7 of the cone being fitted into a countersink, 8, in the top of the tube,:and secured by turning the upper edge of the tube over it, and being shouldered at the bottom, as shown at 9 in Fig. 3, and fitted and riveted into the opening at the top of the chamber, as shown at 10 10 in Fig. 1.

Fig. 5 shows the tip, made ofcast-iron, of one piece, having a groove in the lower part of its eXterior, into which the edges of the hole in the top of the chamber are turned, as shown at 11 11 in Fig. 5.

The chamber may be filled with wool or other fibrous or porons material to break the pressure of the gas and cause its thorough distribution throughout the chamber.

The burner thus constructed is to be placed over an ordinary burner, E, preferably of the fish-tail kind, so that the tip of the latter is just even with the bottom of the chamber B, and its operation is as follows: The gas issuing from the burner E is expanded in the chamber B, and from thence passes into the space e, within the lower part of the tip O, which constitutes a second chamber, from whence it issues through the orilioes b b, producing a broad, fiat flame, which heats both the tip O and the chamber B to such a degree that the expanded gas therein is heated to a high degree before issuing, and its combustion is so perfect that it produces a vastly greater light than is produced by the same quantity of gas with other burners, the flame being both large and bright.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the cap-tube A, the expansionchamber B, and fish-tail tip O, substantially as herein described.
